Countdown Error

Technical Help
#1

@Brian I receive the following error pertaining to my Countdown service every afternoon. My countdown service has the following which includes XCBT, which I thought was required for some Futures data I collect. Please let me know if XCBT is needed, should be replaced with another exchange symbol, or if I should just delete it from my Countdown.

# Collect data from Interactive Brokers each evening at 5:30 PM if the market was open for 15 Minute Futures

I would just pick one exchange and check if it was open. If it was open, the others were open.

@Brian the error is around the XCBT exchange. I received it again tonight and the CBOT was obviously open yesterday and today. As I said I've been receiving this error regularly. The database has successfully collected from the XCBT in the past but I've been ignoring it because it wasn't pressing and now I'm trying to trouble shoot it. Any further guidance would be appreciated. Thanks.

XCBT fails because exchange_calendars (which isopen uses) doesn’t support that particular MIC. You can use CBOT instead. See the choices here.
